BEFORE INSTALLING

This sensor must be installed in compliance with the

control panel system installation manual. The installation

must meet the requirements of the Authority Having

Jurisdiction (AHJ). Sensors offer maximum performance

when installed in compliance with the National Fire

Protection Association (NFPA); see NFPA 72.

GENERAL DESCRIPTION

Models YT202, YT202T are plug-in type photoelectronic

smoke and heat sensors with addressable analog

communications. The sensors transmit an analog

representation of smoke density or temperature over a

communication line to a control panel. Inside MCU's

EEPROM keep the sensor's address that can be set by a

portable Address setting device.

Two LEDs on the sensor are controlled by the panel to

indicate sensor status.

Models YT202T combine a photoelectronic sensing

chamber and 135°F (57.2°C) fixed temperature heat

detector.

The YT202, YT202T require compatible addressable

communications to function properly. Connect these

sensors to listed-compatible control panels only.

WIRING GUIDE

All wiring must be installed in compliance with the

National Electrical Code, applicable local codes, and any

special requirements of the Authority Having Jurisdiction.

Proper wire gauges should be used. The installation wires

should be color-coded to limit wiring mistakes and ease

system troubleshooting. Improper connections will

prevent a system from responding properly in the event of

a fire.

Remove power from the communication line before

installing sensors.

1. Wire the sensor base per the wiring diagram, Figure 1.

2. Set the desired address by portable address setting

device.

3. Install the sensor into the sensor base. Push the sensor

into the base while turning it clockwise to secure it in

place.

4. After all sensors have been installed, apply power to

the control unit and activate the communication line.

5. Test the sensor(s) as described in the TESTING section

of this manual.

Dust covers provide limited protection against

airborne dust particles during shipping. Dust covers

must be removed before the sensors can sense smoke.

Remove sensors prior to heavy remodeling or

construction.

TAMPER-RESISTANCE

Models YT202, YT202T include a tamper-resistant

capability that prevents their removal from the bracket

without the use of a tool.

TESTING

Before testing, notify the proper authorities that the

system is undergoing maintenance, and will temporarily

be out of service. Disable the system to prevent unwanted
